1854 - The first mention of policing in Deddington when it appears that the Parish employed its own constable and built a lock-up in Horsefair at a cost of £248 14s 6d.

25 March 1857 Oxfordshire County Police was formed with the first full-time paid constables working from the army barracks in New Road, Oxford.

1872 The Deddington lock-up was extended to become a police station and was built by Franklin and Sons of Deddington at a cost of £392 9s 8d with Superintendent Seers in charge.

1875 Deddington Magistrates' Court was built, again by Franklin and Sons, and was situated next door to the police station on High Street.

1966 The police station closed as responsibility for policing Deddington had moved to Banbury. It is now a private house (Stoneleigh). However, two new police houses were built on the Hempton Road and constables lived and worked from these houses up until October 1995. The Magistrates' Court is now the Parish Library.

April 2000 A new Police Office opened on the Market Place; it then moved back to the old court house (in 2020 the Library building) on the High Street. Police and Community Support Officers meet here to catch up with paper and online work. At other times it is a drop-in centre staffed by a team of local volunteers and offers community support.

There are 45 licensed premises, 12 schools (age 5–18 years). There are several industrial units across the area, from small sites employing less than twenty up to a large site at Adderbury employing a couple of hundred.

During each year a large music festival is held every August at Cropredy (Fairport Convention) which brings in about 25,000 people for that weekend. In June each year a steam fair rally is held on fields at Bloxham. However, the area is a rural farming community, growing crops and tending livestock. With tourism also having its role to play, there are many bed & breakfast, hotel and camp sites across the area. To this end the police office can advise visitors on local amenities, having a selection of tourist information pamphlets available about the local area, including details about bed & breakfast establishments, and working with Cherwell District Council tourism board.
